Hi

I have a table of data the first 2 columns are Manufacturer and model as varchars.

ie
Manufacturer    Model
Man 1                Mod1
Man 1                Mod 2
Man 1                Mod 3
Man 2                Mod 4
Man 3                Mod 5

Can this be bound such that the top level of the tree shows
Man 1
Man 2
Man 3

And expaned to show the models.

I get an error saying 'This constraint cannort be enabled as not all values have a corresponding parent.
Andy

Hello Andy,

 
By default this kind of binding is not supported by RadTreeView but you can add the nodes one by one by checking if RadTreeView already contains such node as it is done in the attached project.

Hope this will be helpful.
